The singer's jewelry featured a charm that spelled out "Angelo," and sources tell The Sun that's the name of her baby boy.
The child was born in October, and is the first with her fiancé Simon Konecki. Adele has refused to tell reporters the child's name when asked, and denied to comment on it at the Golden Globes.
In other Adele news, the singer will be performing her hit Skyfall at the Oscars, where it is nominated for Best Original Song. She said, "It's an honor to be nominated and terrifyingly wonderful to be singing in front of people who have captured my imagination over and over again. It's something I've never experienced and probably only ever will once!"
